LIFE-SAVING ALPARATUS.

Specification of Letters Patent.

Patented Mar. 1S, li.

Bc it known that we, CLAYTON E. FREDER- iciisox and lvr BxLnwtN, residing, respectively, in the cities of San Francisco and Alameda, counties of San Francisco and .llamedzny and State of California, have invented a new and Improved Life-Saving Apparatus, of which the following is a specification.

This invention. which generally in the nature of an improved life-saving net, is more especially designed for forming a part of lire apparatus for cities, and it has for its object to provide an inexpensive, compact and easily manipulated body catching means, easily mountable upon an auto truck and so arranged. whereby the truck with the catching in xans can be backed up against a burning` building and easily controlled for catching persons who jump from the windows or the top of the said burning` building.

Our invention also has for its object to provide a life saying apparatus of the kind generally outlined in which the apparatus can be almost instantly set up for use by cranking the same and the catching means is readily folded up when not in use.

lilith other objects in view that will be hereinafter apparent, our invention consists in the peculiar arrangement and combination of parts, all of which will be hereinafter explained specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which:

Figure l, is a perspective view of our invention, the saine being shown as adjusted for use. Figs. Q and 3, represent a side elevation of the complete apparatus, the parts being in the folded or traveling position. Fig. 4, a transverse section thereof, the parts being` adjusted for catching the `iuinper. as in Fig. l. Fig. is a similar view. the parts being in their folded or closed position. Fig. 6, is a detail section of the worm drive for opening and closing the net or apron carrying pivoted side arms. Eig. T. is a detail view that shows the manner of connecting the crank shaft with the worin carrying shaft. Fig. S, is a detail view hereinafter referred to.

ln carrying out our invention. and in the preferred form thereof, we employ an auto truck l of any approved type, and which includes the longitudinal angle bars 2 2,

upright brackets S and upon each opposite pair of which, (three opposite pairs being' shown) is mounted a transverse bar 4 that ferins the bed or supportfor the catching means, the peculiar construction of the cooperative parts of which, form the essentials of our invention. The cross bars 4, extend laterally of the trut-i: and on the outer ends of each of the said bars 4 is mounted a bearing box 5, those at each sid-e alining to accommodate the roel; shaft-s C. A series of side bars l" are lixedly connected to each rock shaft G to roel; therewith, the upper ends of which curve upwardly, as at T0, whereby, when the parts are folded or closed, as in F 5, for traveling to and from the place of fire, the several parts will be compactly closed or folded up over the top of the truck.

8 designates a main shaft that extends loir gitudinally of and is disposed midway of the truck, the said shaft being journaled in short upright brackets S0 mounted on the cross bars 4, is best shown in Figs. 4 and 5.

9 designates double grooved guide pulleys, one of which is provided for each opposing pair of side bars 'T and the said pulleys are keyed upon the central or main shaft 8.

10 and Q0 designate cable connections for the opposite side bars T, one of which l0, connects with the upper encs of the arms at one side passes around one part of one of the corresponding double pulleys and passes to and connects with the lower endof the said side arm 7, the other cable 20 likewise connecting the other side b ar 7.

l2 designates a worin on the shaft 8 that meshes with a gear 9 on a transverse shaft 90 journaled in upright brackets 91 that extend up from one of the end cross frames.

Shaft 9 at one end has a lateral stud 92 for cooperating with the soc-liet 93 thatforms part of a crank shaft 94 and which has a bayonet slot 95 for engaging the stud 92.

75 designates a flexible body which nia-y be a netting or an apron, which extends the full length of the side rods 7G that connect the upper ends of the arms 7. The opposite sides of the net or apron 75 are fixedly connected to the said rods 76 and in such a manner so that when the arins 7 are swung out to the position shown in Figs. l and 4, a

yielding net or apron is proi'ided lor eatehing;` the jumper. it being understood that since 'the oppositie ends of the arms 7 are joined with the central or main Shaft by the llexible members that Wind one or more, about their respective drums on the main shaft, said flexible eonneetions will tend to e1 ep en the drums or pulleys when under excess strain and therebyT niaterially oyereoine tendency ot' the ends of the net tearing from the side rods to Which they are eonneeted. lit desired the side edges of the apron or net may be provided with yielding portions in the nature of springs 7S, as shown in Fig. 8. vWhen the arms 'T are. swung' innf'ardly. by cranking` the main shaft. the apron or net will double and hang folded. as shown in Figi; Y

`lfroni the `foregoing' taken in eonneetion with the accompanying dra Wings, the complete Construction, the manner oit its operation and the advantages of our invention will he readily apparent.

lihile the generi] arrangement of the parts as shown and deseribed discloses a prelerred form ot our invention. yet We do not limit ourselres to the exaet details or eoinbination of parts shonn. .since they may be readily moditied or varied and come Within the scope of the appended claims.

lli/hat We claim is:

l. itt portable body eatehing apparatus, comprising a trueli haring a bed 'ramey arms roelably mounted at each side of the bed frame, a eranl; shaft, devices eouneeting` said shaft to said arms at eaeli side oit their tulerums for swinging the Said side arms inwardlhfv and outwardly in a plane at right angles to the trame, and a `flexible body connected at the opposite edges to the side arms and adapted When the side arms are laid last named means including pivotally roelrable side arms and crank actuated means on the bed frame for adjustingr the first said means to dran' out or Yfold up the said net or apron, said crank aetuated means comprisinga centrally longitudinally located Crank shaft. and power transmitting' cable Connections eneireling said .ranl shaft and ha ving their ends seeure-l to the roelable side arms,one end at one side of the pivet and the other end at the other side ot' the pivot of the respective arms.

3. in a liite saving' apparatus or' the eliaraeter described; a bed traine. said traine iueluding Cross bars, a rock shaftr 'For eaeh side of the apparatus journaled in bearings ou the endsy o'll the Cross bars. verticallyv swine# able side arms mounted on eaeh oli the rook shafts to rock therenf'it-h. a longitudinal sha'tt mounted on the bed traine midway of the roel; shafts and haring' Winding` drums, VFlexible eonneetiens wound on the drums, one end of eaeh of the said Connections joiningv with the upper end of its respective side arm, and the other end of the said eonneetions joining` Wit-h the lower end of the said side arm. means for reversely rotating the drum shaft and a tlexible apron or net. Whose opposite ends join with the upper ends of the side arms.
